BICYCLE.

SPECIFICATION forming part of Letters Patent N o. 646,656, dated April3, 1900. Application filed May 11, 1898. Serial No. 680,333. (No modelJ'To all whom it may concern:

Be it known that I, HENRY H. FEEEL, al citizen of the UnitedStates,residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Bicycles, ofwhich the following is a full, clear, and exact description.

This invention relates to safety-bicycles, and embodies improvements inframe construction, as well as driving mechanism.

The object is to .produce a bicycle of the chainless variety which shallbe light, strong, and speedy and which shall provide means whereby powerapplied to a spur-wheel shall be transmitted directly to the hub of therear wheel of the bicycle without the use of intermediate gears or othermoving parts, the pedal movementbeing in a substantially-vertical linerather than rotary.

The invention consists of the details of construction hereinafterdescribed and claimed, and illustrated in the accompanying drawings, inwhich- Y Figure lis a side elevation of my improved bicycle. Fig, 2 is adetail view in plan of a portion of Fig. l, showing the gears and thehub of the 4rear wheel in section; and Fig. 3 is a modified form of myinvention.

Referring to the drawings by letter, A represents the frame proper, andB the front fork,

-mounted thereon in the usual manner and supporting the front orsteering wheel lB. The frame, disregarding the front fork, resembles inoutline a right-angled triangle cut off near to the apex thereof andis'built up of four principal parts-a steering-head D, an upperhorizontal tube E, a lower oblique tube E, and a vertical tube G. Thetubes E and E are forked or bifurcated and have their branches or tinesff and g g connected together in corresponding pairs by the brackets 7c7c. These brackets are similar in construetion and extend, preferably ina horizontal plane, a short distance to the rear of tube F, the rearwheel C, carrying a pinion c on the hub C thereof, being mounted upon ahollow axle O2, flxedly secured between such rearwardly-extendingportions of said brackets 7c k'. One of the aforesaid brackets aords abearing for a spur-wheel N, the spur-wheel standing next to the innerface of t'he bracket adjacent wheel O and engaging with pinion c. Theshaft of the spur-wheel N extends through the bracket and carries on itsouter end a crank n', a similar crank n2, set oppositely thereto, beingcarried on inner end of said shaft. A link m connects crank n with therocking lever M, which, as herein shown, is pivoted concentrically withaxle C2 and is provided on the free end thereof with a suitable pedalm'. As above mentioned and as shown in Fig. 2, axle O2 is provided witha central longitudinal bore c3, through which a rod or shaft p extends,the rod being somewhat longerthanhubcf?. LeverMislooselymount; ed uponone'of the projecting ends of said rod p, between a nut p and an arm R.This arm is keyed or otherwise fixed to rod p and is curved or bent overbracket 7c and behind wheel N and is connected with crank n2 by means ofthe link r. To the opposite end of rod p a lever S, similar to lever M,is keyed or otherwise iixedly secured, the lever S, rod 19, and arm Rforming a practically-integral rocking frame. Both levers M and S areadapted to impart rotary motion to the spurwheel N when properlyactuated, as will be readily understood. The lever M, being loose on rodp, partakes of an independent movement of its own, and the cranks are soset that as Aone lever descends the other ascends,

and two s ur-wheels N N havin@ singlecranks N2 N 2, and each operated byseparate links and levers n3 n3 and n4 n4, respectively.

Having described my invention, I claim- The combination of a suitableframe, a

' wheel mounted therein, a pinion on the hub of said wheel, a spur-wheelmounted on one side of the aforesaid frame engaging said pinion andhaving cranks mounted one on either end of the shaft thereof, a hollowaxle, 2t rod spectively, substantially as and for the pur extendingthrough said axle, a pedal-lever pose described. 1o tightly mounted toone end of said rod or In witness whereof I subscribe my signashaft, :tloosely-mounted pedal-lever and a ture in presence of two Witnesses.
